* Choji Akimichi from ''{{Naruto}}'' is constantly prodded into battle by his allies and enemies who call him fat.
-->'''Choji:''' ''(after one of the Sound Genin calls him "fatso")'' "I'M NOT FAT! IIIII AAAAAAM BIIIIIG BOOOOOOONEEEEEEEED!"
** One of the Sound Four, Jirobo, hits ''two'' of Choji's berserk buttons and a RelativeButton in a single fight--calling him fat and useless, [[LostFoodGrievance eating his last potato chip]] and insulting Shikamaru. In response, Choji takes [[DeadlyUpgrade the third and most powerful of his special food pills]], and it [[spoiler:makes him skinny, gives him magical glowing butterfly wings, and enough raw power to kill Jirobo(in his own Final Form) in one strike.]]
* This exchange from TheMovie is pretty self-explanatory:
--->'''Naruto:''' Man, I don't know where you got your taste in men, Sakura, but it stinks.\\
'''Sakura:''' ''(furiously)'' WHAT DID YOU SAY?!\\
'''Naruto:''' ''(with BlankWhiteEyes and a small voice)'' I'm sorry, what was the question?
** On a more serious note, even mentioning Orochimaru in a respectful fashion in front of Naruto is a good way to activate Naruto's SuperpoweredEvilSide.
*** Speaking of Naruto, you should ''never'' insult the title of Hokage in front of him. He won't care if you're one of the legendary sannin. He won't care if you're a woman. [[PunctuatedForEmphasis He...will...]][-[[PunctuatedForEmphasis KICK]]-][[PunctuatedForEmphasis ...]][-[[PunctuatedForEmphasis YOUR]]-][[PunctuatedForEmphasis ...]]'''[-[[PunctuatedForEmphasis ASS]]-]'''!
** After the timeskip, Naruto and Sakura are both angered by anyone who badmouths Sasuke, or suggests that he is too far gone for them to bring back.
** Speaking of Sakura, '''NEVER''' say that she has a big forehead when she's within earshot. Konohamaru found that out the hard way.
* Never! '''EVER'''! Call Tsunade an [[ObaSan old hag/grandma]]! '''EVER!''' Except if you're Naruto, who uses it more as an affectionate nickname.
* [[ChristmasCake The Fifth Mizukage]] does NOT like anyone implying that she's in danger of ending up an old maid. [[TwistingTheWords Even if they're not]].
* One filler arc pre-TimeSkip gives Naruto another BerserkButton. An imposter is going around Konoha, ruining Naruto's reputation (and his good credit at the local restaurants). Worn out from trying to clear his name, Naruto starts to head home...then has a major OhCrap moment and rushes all the way back there to find that [[spoiler:the imposter ate his entire supply of beef ramen that he was stockpiling]]. Cue SuperpoweredEvilSide breaking out.
* Initially, Sasuke's berserk button was simply mentioning his brother, it changed to a RelativeButton and a extra BerserkButton now it's mentioning his brother in a disrespectful way. Or if you mention his clan...or have a Sharingan "That you don't deserve".
* Kakashi REALLY hates Orochimaru and Kabuto's Edo Tensei (Summoning: Impure World Resurrection) technique, which they use to revive dead shinobi and force them to fight. In fact having to fight an Edo zombie is the first thing in the manga that visibly made him rage. In fact he really seems to hate Kabuto in general.
* It doesn't take much for Deidara to flip his shit, but if you call his art inferior (or a cheap rip-off)...run.
* Don't ever claim that names don't matter to Kabuto.
* The Nine-Tailed Fox, Kurama, really, really hates [[spoiler:Madara]]. His mere presence was enough for Kurama to instantly offer an EnemyMine team-up with Naruto.
** It was understated at the time, but [[spoiler: Kurama ''really did not like'' Pain's view of the world.]] It irritated to much that he inadvertantly [[spoiler: synchronized his own chakra to match Naruto's and the natural chakra Naruto had gathered]] just to have a part in the fight. [[spoiler: doubles as ExoticEyeDesigns, because his fox eyes overlapped with Naruto's frog eyes to give him some kind of freaky orange cross eyes.]]
* Do NOT mention the 1st Hokage around [[spoiler: Madara]].
** One other BerserkButton for him: [[spoiler: Don't stand behind him when he pees, it '''irritates''' the hell out of him. Something Hashirama was fond of doing, just to get a rise out of him. No wonder he hates the man to this day.]]
* Don't call Yagura a kid. He may look like one, but he's actually an [[OlderThanTheyLook adult]] [[spoiler: and the Fourth Mizukage as well]].
